2018-12-19[ARM] Optimize executable size when using softfloat fmul/dmulThomas Preud'homme
Softfloat single precision and double precision floating-point multiplication routines in libgcc share some code with the floating-point division of their corresponding precision. As the code is structured now, this leads to *all* division code being pulled in an executable in softfloat mode even if only multiplication is performed. This patch create some new LIB1ASMFUNCS macros to also build files with just the multiplication and shared code as weak symbols. By putting these earlier in the static library, they can then be picked up when only multiplication is used and they are overriden by the global definition in the existing file containing both multiplication and division code when division is needed. The patch also removes changes made to the FUNC_START and ARM_FUNC_START macros in r218124 since the intent was to put multiplication and division code into their own section in a later patch to achieve the same size optimization. That approach relied on specific section layout to ensure multiplication and division were not too far from the shared bit of code in order to the branches to be within range. Due to lack of guarantee regarding section layout, in particular with all the possibility of linker scripts, this approach was chosen instead. This patch keeps the two testcases that were posted by Tony Wang on the mailing list to implement this approach and adds a new one. 2018-12-19 Thomas Preud'homme <thomas.preudhomme@linaro.org> libgcc/ * /config/arm/lib1funcs.S (FUNC_START): Remove unused sp_section parameter and corresponding code.

Currently, .cfi_endproc and FUNC_END(__trampoline_setup) are placed inside the #else branch of an "#if defined (__VXWORKS__) ...", so non-pic vxworks does not get proper CFI nor a .size directive for __trampoline_setup.

2018-11-27[RS6000] libgcc cfiAlan Modra
There are a few places in libgcc assembly where we don't emit call frame information for functions, potentially breaking unwinding from asynchronous signal handlers. This patch fixes them. Although I patch tramp.S there is no attempt made to provide CFI for the actual trampoline on the stack. Doing that would require generating CFI at run time and both registering and deregistering it, which is probably not worth doing since it would significantly slow down the call. * config/rs6000/morestack.S (__stack_split_initialize), (__morestack_get_guard, __morestack_set_guard), (__morestack_make_guard): Provide CFI covering these functions. * config/rs6000/tramp.S (__trampoline_setup): Likewise.

2018-10-31Update GCC to autoconf 2.69, automake 1.15.1 (PR bootstrap/82856).Joseph Myers
This patch updates GCC to use autoconf 2.69 and automake 1.15.1. (That's not the latest automake version, but it's the one used by binutils-gdb, with which consistency is desirable, and in any case seems a useful incremental update that should make a future update to 1.16.1 easier.) The changes are generally similar to the binutils-gdb ones, and are copied from there where shared files and directories are involved (there are some further changes to such shared directories, however, which I'd expect to apply to binutils-gdb once this patch is in GCC). Largely, obsolete AC_PREREQ calls are removed, while many AC_LANG_SOURCE calls are added to avoid warnings from aclocal and autoconf. Multilib support is no longer included in core automake, meaning that multilib.am needs copying from automake's contrib directory into the GCC source tree. Autoconf 2.69 has Go support, so local copies of that support are removed. I hope the D support will soon be submitted to upstream autoconf so the local copy of that can be removed in a future update. Changes to how automake generates runtest calls mean quotes are removed from RUNTEST definitions in five lib*/testsuite/Makefile.am files (libatomic, libgomp, libitm, libphobos, libvtv; some others have RUNTEST definitions without quotes, which are still OK); libgo and libphobos also get -Wno-override added to AM_INIT_AUTOMAKE so those overrides of RUNTEST do not generate automake warnings. Note that the regeneration did not include regeneration of fixincludes/config.h.in (attempting such regeneration resulted in all the USED_FOR_TARGET conditionals disappearing; and I don't see anything in the fixincludes/ directory that would result in such conditionals being generated, unlike in the gcc/ directory). Also note that libvtv/testsuite/other-tests/Makefile.in was not regenerated; that directory is not listed as a subdirectory for which Makefile.in gets regenerated by calling "automake" in libvtv/, so I'm not sure how it's meant to be regenerated. While I mostly fixed warnings should running aclocal / automake / autoconf, there were various such warnings from automake in the libgfortran, libgo, libgomp, liboffloadmic, libsanitizer, libphobos directories that I did not fix, preferring to leave those to the relevant subsystem maintainers. Specifically, most of those warnings were of the following form (example from libgfortran): Makefile.am:48: warning: source file 'caf/single.c' is in a subdirectory, Makefile.am:48: but option 'subdir-objects' is disabled automake: warning: possible forward-incompatibility. automake: At least a source file is in a subdirectory, but the 'subdir-objects' automake: automake option hasn't been enabled. For now, the corresponding output automake: object file(s) will be placed in the top-level directory. However, automake: this behaviour will change in future Automake versions: they will automake: unconditionally cause object files to be placed in the same subdirectory automake: of the corresponding sources. automake: You are advised to start using 'subdir-objects' option throughout your automake: project, to avoid future incompatibilities. I think it's best for the relevant maintainers to add subdir-objects and do any other associated Makefile.am changes needed. In some cases the paths in the warnings involved ../; I don't know if that adds any extra complications to the use of subdir-objects. I've tested this with native, cross and Canadian cross builds. The risk of any OS-specific issues should I hope be rather lower than if a libtool upgrade were included (we *should* do such an upgrade at some point, but it's more complicated - it involves identifying all our local libtool changes to see if any aren't included in the upstream version we update to, and reverting an upstream libtool patch that's inappropriate for use in GCC); I think it would be better to get this update into GCC so that people can test in different configurations and we can fix any issues found, rather than to try to get more and more testing done before it goes in. top level: 2018-10-31 Joseph Myers <joseph@codesourcery.com> PR bootstrap/82856 * multilib.am: New file.

2018-10-17libgcc: apply LIB2FUNCS_EXCLUDE logic to LIB2FUNCS_STRasmus Villemoes
One target file (config/c6x/t-elf) lists _printf and _gcc_bcmp in LIB2FUNCS_EXCLUDE, but that does not have any effect, since those are not filtered away from LIB2FUNCS_ST. Another option is to do as in config/rl78/t-rl78, which explicitly sets LIB2FUNCS_ST # Remove __gcc_bcmp from LIB2FUNCS_ST LIB2FUNCS_ST = _eprintf but honouring LIB2FUNCS_EXCLUDE also for LIB2FUNCS_ST seems more natural.

2018-08-23PR target/86951 arm - Handle speculation barriers on pre-armv7 CPUsRichard Earnshaw
The AArch32 instruction sets prior to Armv7 do not define the ISB and DSB instructions that are needed to form a speculation barrier. While I do not know of any instances of cores based on those instruction sets being vulnerable to speculative side channel attacks it is possible to run code built for those ISAs on more recent hardware where they would become vulnerable. This patch works around this by using a library call added to libgcc. That code can then take any platform-specific actions necessary to ensure safety. For the moment I've only handled two cases: the library code being built for armv7 or later anyway and running on Linux. On Linux we can handle this by calling the kernel function that will flush a small amount of cache. Such a sequence ends with a ISB+DSB sequence if running on an Armv7 or later CPU. gcc: PR target/86951 * config/arm/arm-protos.h (arm_emit_speculation_barrier): New prototype. * config/arm/arm.c (speculation_barrier_libfunc): New static variable. (arm_init_libfuncs): Initialize it.
